RELA² is one of the most accurate smart activity trackers on the market period!
Why is that so? it is only off by +/- 5 BPMS though not really medical grade (250 takes per second) this is the closest you could get to.
It is worn on the upper part of the art and it has a one size fits all band that is able to fit literally anyone.
The reason it is placed in the upper part of the arm is to make sure that the readings are accurate, other trackers place these types of sensors right above the chest or main artery which makes them at times a bit harder to wear.
It is compatible with all the major Sports and Fitness apps, such as Polar Fit, Wahoo, strava, runtastic etc
It has a 7 day in built memory, IP67 Water and Dust resistant using both Bluetooth and ANT+ Connectivity.
It comes in 4 different colors of straps and it could also be aggregated and projected on to a single screen for those fitness & data bunnies who want to see how well they are doing during the training
NOTE: The Group Fitness Collector is another device of its own and needs to be bought separately.
